Why density of cotton is low?

Why density of cotton is low?

Water is liquid and has more density than air and exhaust from chimneys because particles of water have more force of attraction. Cotton is a type of solid because they have definite mass, size and volume. Thus, cotton is denser than air, exhaust from chimneys and honey.

What is the density of cotton?

1.54 – 1.56 g/cm³

At what temperature water has maximum density give reason?

4°C

At which condition density becomes maximum a/p 0.5 atm and T 600 K B P 2 atm and T 150k c/p 1 atm and T 500 K’d p 1.5 atm and T 400 K?

Explanation: An ideal gas will have maximum density at high pressure and low temperature i.e. when P = 2 atm, T = 150 K.

When the density of gas is maximum?

The density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density. The result is that warm gases rise and cool gases sink. The same concept helps to explain the weather resulting in high and low pressures.

What is the density of an ideal gas?

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.

What is the value of STP?

Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar).

What is STP formula?

What is STP? STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density and is represented as STP = V*(273/T)*(P/100) or stp = Volume of Gas*(273/Temperature of Gas)*(Pressure of Gas/100).

Is STP and NTP are same?

STP is the standard temperature and pressure and NTP is the normal temperature and pressure. As per IUPAC, the STP value of temperature and pressure for gas is 273.15 K and 0.987 atm respectively. The NTP value of temperature and pressure is 293.15 K and 1atm.

What is STP mean?

reference point of temperature and pressure

What is STP positive?

STP Medical Abbreviation. 5. STP. Standard Temperature and Pressure + 1 variant.

Is STP still in business?

STP is an American brand of automotive aftermarket products, especially lubricants such as motor oil and motor oil additives. The name began as an abbreviation of Scientifically Treated Petroleum. The brand is owned by Energizer Holdings, which acquired STP in November 2018.
